Description

Technical Field

[0001] This utility model relates to the field of grain and oil processing technology, specifically to an extrusion device for grain and oil processing. Background Technology

[0002] Grain and oil crops (such as soybeans, peanuts, rapeseed, and corn germ) and their processed oils are a collective term for food crops and their processed oils, serving as an important source of energy and nutrition in the human diet. The core objective of grain and oil processing is to extract oils through physical or chemical methods while preserving nutrients and controlling the content of harmful substances. The extrusion unit is a key piece of equipment in grain and oil processing. Its core function is to break down the cell structure of oilseeds through mechanical force and promote the release of oil. Compared with traditional hydraulic pressing or solvent extraction, the extrusion unit has the following advantages: it integrates crushing, pressing and deslag removal, reducing the number of process steps; continuous operation increases production capacity and is suitable for large-scale production; therefore, the extrusion unit plays an irreplaceable role in the production of edible oil, biodiesel and industrial oils.

[0003] Existing extrusion devices (such as screw-type and hydraulic-type) generally suffer from technical defects such as uneven feeding and easy clogging. Specifically, these defects manifest as: material accumulation and backflow: design flaws in the feed inlet (such as a straight-cylinder structure) cause material to accumulate at the inlet, preventing synchronous advancement with the screw; uneven particle size (such as a mixture of whole peanuts and crushed material) leads to backflow, reducing pressing efficiency. Moisture and viscosity also affect performance: high-moisture materials (such as fresh rice bran) easily adhere to the inner wall of the feed hopper, forming a crusty layer; low-viscosity materials (such as shelled sunflower seeds) have excessive fluidity, causing uncontrolled feeding speed. These problems reduce pressing efficiency, increase the oil content of the residue, and increase equipment maintenance costs. Therefore, a new extrusion device for grain and oil processing is proposed to address these issues. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1: Please see Figure 1-6This embodiment of an extrusion device for grain and oil processing includes a machine body 1, which includes a support frame 11 for support. The machine body 1 is also provided with an oil pressing chamber 12 for processing grain raw materials. The oil pressing chamber 12 has an opening, and an oil discharge hopper 13 for guiding grain and oil is connected to the opening. The support frame 11 is also provided with a transmission component 14 for transmission. The output shaft of the transmission component 14 is driven to a motor reducer, and a transmission wheel 15 is provided on the output shaft. The transmission wheel 15 is driven to a linkage component 4 through a transmission belt 16. The linkage component 4 is driven to a feeding component 2 for easy feeding. The output end of the motor reducer is driven to an extrusion component 3 for pressing oil. The extrusion component 3 is located in the oil pressing chamber 12, and a discharge hopper 17 for discharging oil pressing residue is connected to the extrusion component 3. In actual use, when it is necessary to press oil from raw materials, the raw materials can be put into the feeding component 2. Then, the operator can start the transmission component 14 to make its output shaft rotate. During the rotation of its output shaft, the transmission wheel 15 and the transmission belt 16 can drive the linkage component 4 to move. During the movement of the linkage component 4, the feeding component 2 can be driven to achieve the effect of conveying and stirring the raw materials, thereby avoiding the accumulation of raw materials and the occurrence of blockage. Meanwhile, during the rotation of the output shaft of the transmission component 14, the drive motor reducer can effectively drive the extrusion component 3 to achieve the effect of pressing the grain and oil raw materials, ensuring its linkage during use.

[0016] The technical effects of the above embodiments are as follows: by setting the feeding component 2, the raw materials can be effectively fed and stirred during use, thereby effectively avoiding the accumulation or blockage of raw materials when they enter the extrusion component 3, effectively avoiding the need for staff to stop the machine for cleaning, ensuring the stability of the device during use, and increasing its oil extraction efficiency.

[0017] As a preferred technical solution in this embodiment: the feeding assembly 2 includes a feeding hopper 21 installed on the top of the oil pressing chamber 12.

A connecting shaft 23 is rotatably connected to the support plate 22. The bottom of the connecting shaft 23 extends into the interior of the feeding hopper 21 and is fixedly connected to an anti-blocking component 24. By providing the anti-blocking component 24, the operator can effectively ensure that the connecting shaft 23 can achieve a good conveying effect on the raw materials when controlling its rotation, thereby ensuring its stability during use. The support plate 22 and the connecting shaft 23 ensure good rotation effect during use.

[0018] As a preferred technical solution in this embodiment: the anti-clogging component 24 includes a connecting rod 241 mounted on the connecting shaft 23, a screw conveyor blade 242 for conveying raw materials on the connecting rod 241, and a mounting base 243 fixedly connected to the bottom of the connecting rod 241. The mounting base 243 is equipped with multiple stirring rods 244 for agitating the oil extraction raw materials. In actual use, as the connecting rod 241 rotates, it drives the screw conveyor blade 242 to rotate. When the screw conveyor blade 242 rotates, it effectively conveys the raw materials and simultaneously drives the stirring rods 244 and the mounting base 243 to agitate the raw materials, thereby preventing the accumulation of raw materials when entering the extrusion assembly 3.

[0019] As a preferred technical solution in this embodiment: the linkage component 4 includes a support base 41 for support, a linkage shaft 42 rotatably connected to the support base 41, a linkage wheel 43 fixedly connected to one end of the linkage shaft 42 and driven by the transmission belt 16, and one end of the linkage shaft 42 extends into the protective housing and is provided with a worm gear 44 for transmission, the worm gear 44 being driven by a worm wheel 45, and the worm wheel 45 being fixedly installed on the connecting shaft 23. In actual use, when the operator controls the transmission wheel 15 and the transmission belt 16 to drive the linkage wheel 43 to rotate, the linkage wheel 43 can drive the linkage shaft 42 to rotate the worm gear 44. During the rotation of the worm gear 44, it can drive the worm wheel 45 to rotate the connecting shaft 23, thereby enabling the connecting shaft 23 to drive the anti-blocking component 24 to achieve the effect of conveying raw materials.

[0020] The technical effects of the above embodiments are as follows: by setting the linkage component 4, it can have a good linkage effect during use, thereby ensuring that the device requires less structure during use, saving energy waste, and effectively ensuring its stability during use.

In actual use, when the operator controls the output shaft of the transmission component 14 to rotate, the output shaft can drive the motor reducer to make the first screw 38 rotate. During the rotation of the first screw 38, the oil-pressing raw material in the feed hole 35 can be conveyed and squeezed, thus ensuring that the raw material can be pressed for oil during use. After the oil is pressed in the feed hole 35, the raw material can be conveyed to the second filter screen 37. Then the second screw 39 will perform a second pressing and oil-pressing effect on the raw material. Finally, it can be discharged through the discharge hopper 17.
